YETI Rambler 10 oz Wine Tumbler, Vacuum Insulated, Stainless Steel with MagSlider Lid - Seafoam The Rambler 10 oz Wine Tumbler is made from durable stainless steel with double-wall vacuum insulation to protect your hot or cold beverage at all costs. Rambler comes with the YETI MagSlider Lid, the only drink lid that uses the power of magnets to keep your favorite drink on lock. While the MagSlider Lid adds a barrier of protection for keeping drinks contained and preventing heat or cold from escaping, Please Note – The MagSlider Lid is not leakproof and will not prevent spills. YETI Ramblers are BPA-free, dishwasher safe, and have a No Sweat Design to make sure your hands stay dry. The tough Duracoat coating on the colored tumblers won’t crack, peel or fade. While most things are better outdoors, it’s especially true of wine. Now, enjoying your wine in the wild is simultaneously hard core and laid back. Each measures 4.5 in high and 3.5 in wide.
